Those calabooses with only room obviously belong in the category of a building with only one cell. They are usually the smallest and most common. I have documented 38 calabooses with only one room. In a few cases, there are examples that have a room behind bars that was obviously a cell. These calabooses also have a small open room that was probably used by law enforcement as a place for a small desk or just to be able to get out of the weather when dealing with prisoners.
Those calabooses with only one cell include Bedias, Best, Burlington, Carbon, Chillicothe, Deport, Desdemona, Florence, Fort Griffin, Gause, Glazier, Grapevine, Henrietta, Hermleigh, Hondo, Jewett, Kemp, La Grange, Lakeview, Leonard, Merle, Monahans, Moran, Odell, Pilot Point, Riesel, Ringgold, Rowena, Santa Anna, Skidmore, Snook, Stiles, Stockdale, Tioga, Trenton, Turkey, Weimar, and Weesatche.
Some calabooses have two cells. However, there are some examples with two rooms and it is not known if both rooms were used as cells. In Leonard, for example, there are two rooms. The room to the right is only guarded by the single door that allows entry into the building. To the left is a room behind a wall of bars that was obviously a cell. It is also possible that both rooms were used as cells but since this does not appear to be the case the calaboose in Leonard is classified for now as a one with a single cell. The calaboose in Turkey has a small room in the back that is behind a wall with bars. This is similar to the Leonard example except that in Turkey the rooms are in a straight line and the front room is much larger than the cell in the back. The large room could have been used as a holding tank for drunks and the cell could have served as a secure place for the more serious criminals that needed to be segregated from the main population or held for a longer period of time.
Those calabooses with two cells include Arp, Boling, Caldwell, Cameron, Clifton, Crawford, D’Hanis, Eagle Lake, East Bernard, Flatonia, Frisco, Goldsmith, Grapeland, Holland, Holliday, Hubbard City, La Coste, McGregor, Miles, Rosebud, Royse City, San Marcos, Somerville, Thorndale, Van Alystine, and Wortham.
Bartlett, Eden, and Granger are the only towns with calabooses that have three cells.
